On 10th August 2020, a CAT archaeologist observed the reduction of an area measuring 39.9m� by up to 0.45m to accommodate the new extension. Archaeological monitoring was carried out at Shore House, The Quay, Burnham-on-Crouch, Essex during groundworks for a single-storey rear extension. Shore House is an 18th-century Grade II listed building which lies in the historic core of Burnham-on-Crouch, which has its origins in the medieval period. Excavation of the site revealed an 18th-century layer of made ground which was presumably laid as part of the construction of Shore House. No further remains were encountered as the groundworks did not penetrate beyond post-medieval layers.
